No, it's not a joke. It's quite common that other confirmers have been able to playback a recording while you can't. It's a matter of different operating systems, machine setups and settings etc.

But if you make a recording and it doesn't playback even for you on same machine... then the odds that someone else would be able to playback it properly are close to zero. If you submit such a score then you are wasting other people's time who may spend a lot of time to try and playback the recording. One should always check out that the recording playbacks properly - ESPECIALLY with a game which has playback issues (usually games with analog controls aka mouse/joystick).

If you can't playback your own score... try recording again with different MAME settings/versions etc.

Give me an examble. An inp which a confirmer may play, but someone else cannot.

Actually, what he said with some paraphrasing from me was that if the person who recorded it can't even play it back using the same physical machine, operating system, roms and version of Mame then it's highly unlikely anyone else will be able to play it back either on their machine which is obviously a different physical machine and potentially a different OS as well.

In other words, you wouldn't have encountered this, due to being relatively new, but TJT and others have been around long enough to know that Windows XP vs Windows 7 vs Win95 vs ... etc could make a difference to the success/failure of the playback even though the roms and Mame version used to attempt the playback were identical. Sometimes, even just a faster/different CPU but the same OS, roms and Mame version would be enough to make things go wrong, especially on games that are pushing the physical hardware to it's limits in order to run the emulation as that can make timing differences in CPU cycles etc affect the resulting runtime emulation. Other games also have issues with desynching if you are skipping frames, such as a lot of early Sega games. Those games may have been using things like raster interrupts or similar to do some of their time/randomness routines and skipped frames = missing IRQs = desync etc.

EDIT ok, now it does not play for me neither. I don't know what happens, via mame 169,182,183 shows stage 1 played in same way, then desyncs in stage 2.
But I swear, I was able to playback it normally to 902k. I did it twice. I can easily remake 902k or more, just wonder why this happens.
Can an experienced mamer give a thinking?
